Arenko has signed a trading optimisation services agreement with Vattenfall’s Pen y Cymoedd 228MW Wind Farm, co-located with battery in South Wales.

Vattenfall’s 22MW was the first in the UK to be co located at a wind farm site, allowing it to benefit from  the existing wind farm grid export connection. The battery, which is made up of  500 BMW i3 battery packs housed in shipping containers, was one of the eight projects selected by National Grid to provide EFR (Enhanced Frequency Response) until February 2022.

From February 2022 onwards, Arenko will use end-to-end trade optimisation and automated dispatch software to maximise returns. The cloud-based optimisation software forecasts market conditions, performing millions of simulations per day to optimise trading decisions, it then securely dispatches stored energy from the assets. Optimising trading increases ROI and streamlines processes for flexible assets when decisions have to be made with ever-increasing speed.

This contract builds upon recent contract wins as Arenko’s technology aids its customers by enabling the flexibility required to support the global transition to a zero-carbon future. Arenko was pleased to work closely with Jake Dunn, Commercial Manager at Vattenfall who pioneered the development of renewables co location in the UK, to finalise this agreement.

Jake Dunn, commercial manager at Vattenfall, said, “Our goal is to enable fossil fuel free living within one generation. We are determined to help this energy transition not just through renewable generation but also supporting grid stability through co-located battery storage projects. As the EFR contract comes to an end and the battery moves to a more diverse range of ancillary services, we are grateful to be assisted in this by the market leading expertise of Arenko.”
